IGN.com has their previews up for the PS2/Xbox versions of NCAA 2007 and the new NCAA 360 for the newer Xbox 360 system. It's too much to sum the IGN reviews up here so I'll simply provide links.
NCAA 2007 for PS2 and XBox
NCAA 360 for Xbox 360
All I'll say about the new 360 version is...wow. Check out these 2 screen shots from IGN. Jaw dropping.
Incredibly impressive. BTW -- here's another custom cover I did last year. This one for Danny Ware.
